Ezra 10:7-9

7They circulated a proclamation throughout Judah and Jerusalem that all the exiles should gather at Jerusalem.

8Whoever did not come within three days would forfeit all his possessions, according to the decision of the leaders and elders, and would be excluded from the assembly of the exiles.

9So all the men of Judah and Benjamin gathered in Jerusalem within the three days. On the twentieth day of the ninth month, all the people sat in the square at the house of God, trembling because of this matter and because of the heavy rain.
